Question

Help please. Im trying to do my homework but i don't understand how to.

Answer 1

V = (4/3) pi  r^3

9.  V = (4/3)(3.14)(7.62)^3 = 1852.4  meters^3
10. V = (4/3)(3.14)(33/2)^3 = 18,807.0  inches^3
11. V = (4/3)(3.14)(18.4/2)^3 = 3260.1  feet^3
12. V = (4/3)(3.14)(sqrt3)/2)^3 = 2.7 cm^3
13. C = 2*pi*r ;   24 = 2 * 3.14 * r;   24/6.28 = r ; r = 3.82
   V = (4/3)(3.14)(3.82)^3 = 233.4 in^3
14.V = (4/3)(3.14)(35.8)^3 = 192,095.6  mm^3

I can't read # 15 but follow the steps above.
